Other Meshtastic Networks in the Area

NoVA Mesh

  • Frequency Slot: 9
  • Private MQTT Server: Yes (restricted access)
  • Network Policy: Gatekept - selective access only

Note: NoVA Mesh uses their own private MQTT server and gatekeeps who connects to the network. They will not provide MQTT information publicly.

DC Mesh

  • Discord: discord.gg/cp87DSyJRz
  • Frequency Slot: 20 (same as DMV Mesh)
  • Compatibility: Automatic node discovery
  • Recommended Topic: msh/US/DMV

Note: DC Mesh operates on the same frequency slot (20) as DMV Mesh, so you should automatically see all DC mesh nodes in the area. We recommend using the msh/US/DMV topic to ensure communication even when no local nodes are available.

Northeast Maryland Amateur Radio Club

Note: Another mesh network that does not use MQTT, so if you are in the area, great! If you cannot connect to them over LoRA you will not be able to join their network.

Richmond Virginia Area Mesh Network

Note: Friendly group of people who are just starting to build out their mesh network! If you live in the area go ahead and join their Discord and help!

Maryland Mesh Network

  • Discord: discord.gg/H9HQANgWTU
  • MQTT Root Topic: msh/US/MD
  • Channel: LongFast (default)
  • Frequency Slot: 20 (assumed default)

Note: Another group of people helping setup Meshtastic over Maryland! MQTT is enabled so if you have a node with no neighboring nodes, then you can still communicate with people!

About Meshtastic

Meshtastic is an innovative, open-source project designed to provide reliable, secure, and decentralized communication using LoRa (Long Range) radio technology. Ideal for situations where cellular networks or Wi-Fi are unavailable or unreliable, Meshtastic enables users to exchange text messages, share locations, and transmit sensor data over considerable distances.

Leveraging the power of LoRa, Meshtastic creates a mesh network, automatically routing messages between nodes to extend coverage beyond the direct reach of a single device. This decentralized approach ensures robust communication, as each device acts as both a transmitter and receiver, seamlessly passing messages through the network.

Common use cases for Meshtastic include outdoor adventures, disaster preparedness, remote sensor monitoring, and community communication networks. Its simplicity and low power requirements make it an excellent solution for staying connected when traditional infrastructure is compromised or unavailable.
